WITNESSETH



WHEREAS, the Subscribers
previously entered into the Warrant Subscription Agreement, dated as of November 15, 2010 (the “Subscription Agreement”;
capitalized terms used without definition herein shall have the meanings assigned to them in the Subscription Agreement), pursuant
to which such affiliates of the Subscribers purchased the Warrants;



WHEREAS, the Subscribers
are in the process of transferring their warrants to their affiliated corporate or trust entities, such transfers expected to become
effective during August 2012, as described on Schedule A attached hereto, with the current warrant ownership of the Subscribers
reflected on the Subscribers’ signature page hereto and the expected warrant ownership of their transferees reflected on
the transferees’ signature page hereto;



WHEREAS, Section 8.1
of the Subscription Agreement provided that the Warrants shall be terminated upon the dissolution of the Company in the event that
the Company does not consummate a Business Transaction within 21 months from the consummation of the IPO; and



WHEREAS, the parties
wish to amend Section 8.1 of the Subscription Agreement to reflect a three-month extension of the deadline for consummation of
the Business Transaction, to provide that the Warrants shall instead be terminated upon the dissolution of the Company in the event
that the Company does not consummate a Business Transaction within 24 months from the consummation of the IPO.



NOW, THEREFORE, for
and in consideration of the premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto do hereby agree as follows:



1.             Amendments.



a.          Address
for Notices. The Company’s address for notices, as set forth in the preamble to the Subscription Agreement, is hereby
changed to Level 9 Podium, 530 Collins Street, facsimile +61 3 9012 7475.



b.          Extension.
Section 8.1 of the Subscription Agreement is hereby amended and restated in its entirety so as to read as follows:



“8.1.      Failure
to Consummate Business Transaction. The Warrants shall be terminated upon the dissolution of the Company in the event that
the Company does not consummate a Business Transaction within 24 months from the consummation of the IPO.”











2.             Full
Force and Effect. Except as expressly amended hereby, each provision of the Subscription Agreement shall remain in full force
and effect.



3.             Miscellaneous.



a.           Governing
Law. This Amendment shall for all purposes be deemed to be made under and shall be governed by and construed in accordance
with the laws of the State of New York.



b.           Headings.
The headings contained in this Amendment are for reference purposes only and shall not affect in any way the meaning or interpretation
thereof.



c.           Counterparts.
This Amendment may be executed in several counterparts, each one of which shall constitute an original and together shall constitute
one instrument. If any signature hereto is delivered by facsimile transmission or by e-mail delivery of a “.PDF” format
data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature
is executed) with the same force and effect as if such facsimile or “.PDF” signature page were an original thereof.
